Abstract
A method is disclosed to signal that a parking brake of an automatic or automated transmission of a motor vehicle is not engaged, during the detection that the driver or passenger door has been opened after the engine has been turned off, characterised in that a vehicle computing unit other than the transmission computer records the last signal related to the engaged state of the parking brake and triggers an alert signal conveyed to the passengers of the vehicle if the driver or passenger door is open and the parking device of the transmission is not engaged.
Description
Technical field
The present invention relates to a kind of Alert Policy (being called as " enabling alarm ") be equipped with on the vehicle of automatic transmission with hydraulic torque converter, these automatic transmission with hydraulic torque converters are equipped with electric parking finger function.
More properly, its target is a kind of method for sending the still unassembled signal of Parking Brake be associated with automatic or automation motor vehicle transmission after being closed at driving engine.
The present invention especially but be not exclusively applicable to the vehicle being equipped with the automatic transmission with hydraulic torque converter being equipped with electric parking finger.
Background technology
In order to avoid the security risk owing to fixedly not causing with the vehicle of automatic or automatic gearbox, before chaufeur leaves vehicle, his or she change-speed box is importantly warned not to be in the fact of " parking " pattern.
According to known arrangement, sending by detecting that driver door opens and is by showing message on the dash panel to carry out of alarm.Publication US 5 956 088 discloses such by the monitoring of the position of the select lever to automatic transmission with hydraulic torque converter and the combined method of the activation of alarm signal.
But this publication does not solve and the vehicle not safety problem that associates of Stationary liquid in all cases.Specifically, if the automatic transmission with hydraulic torque converter computing machine that monitor the joint situation of Parking Brake when leaving vehicle is unactivated, then there will be no the control of the joint about Parking Brake.
Summary of the invention
The present invention seeks to ensure driving engine be closed after " door opens alarm " to vehicle.
So far, what propose is the last signal that a vehicle calculating unit record beyond change-speed box computing machine is relevant to the engagement state of Parking Brake, although and if automatically or the parking device of automatic gearbox not yet engage but chaufeur or the door of passenger open, note to cause the passenger in vehicle with regard to alert trigger signal.
According to the present invention, the storage of engagement state signal is processed by a computing machine still active after change-speed box computing machine has been closed of vehicle.
Preferably, alert message is sent by the computing machine be associated with the vehicle-mounted control part of vehicle.
Accompanying drawing explanation
By to read the following explanation of non-limiting example of the present invention and see accompanying drawing, other features and advantages of the present invention will become cheer and bright, illustrate this strategy in individual figure.
Detailed description of the invention
The instrument carrier panel of vehicle has its oneself the computing machine be associated with various vehicle-mounted control part usually.Automatic transmission with hydraulic torque converter (AT) also has its oneself.When normal running, that is, when automatic transmission with hydraulic torque converter (AT) runs, its computing machine is continued to inform " driving engine operation ", also and the engagement state of Parking Brake and/or the position of gear selector.The computing machine of AT can transmit the state of this concrete function of change-speed box to instrument carrier panel by the data transmission network of vehicle (such as, its network or " CAN " (controller local area network) bus).So computer in the dashboard has the possibility of reacting as " subordinate (slave) " AT computing machine " order " using alarm function, thus the joint of occupant about Parking Brake of warning vehicle or the situation of disengaged condition.Therefore, " door is opened " alarm can be sent from instrument carrier panel in time by alert message.
In principle, different computing machines can ensure to detect that the door of chaufeur is opened.But, for continuity, transversality and the reason of variant part these functions being assigned to system, be often that automatic transmission with hydraulic torque converter computing machine oneself manages this alarm, as indicated in the top of finger.In all cases, " door opens alarm " function relates to monitoring door contact and process " door is opened " information.When normal vehicle operation, therefore the management of alarm relates to the computing machine of AT.If meet following two conditions, generate alarm: " door is opened " and " not engaging parking ".Then, the computing machine of AT is made and the message corresponding with " door is opened " alarm being sent by CAN.The risk that this CAN message is being emitted by instrument carrier panel or any other man-machine interface (HMI) occupant be used in warning vehicle.
Optimize reason for power consumption, if no longer for automatic transmission with hydraulic torque converter provides electric power after driving engine is closed, then also can be stopped by the state of the transmission Parking Brake of CAN by the computing machine of AT.Not regeneration " door is opened " alarm, even if it is also like this that parking finger does not engage.The solution of the head it off proposed depends in the intervention calculating the untapped computing machine of alarm value fashion.Therefore have selected the computing machine beyond AT computing machine and computing machine still active after the computer shutdown of this AT.The preferably computing machine of instrument carrier panel, this computing machine disappears in CAN message and stores the last value of the message corresponding with the parking/non-parked state of change-speed box.Any other calculating unit (if it is associated with man-machine interface) of vehicle can also be made to contribute to the alarm signal preferably sent by the computing machine be associated with the vehicle-mounted control part of vehicle.
As indicated in the middle body of figure, once the computing machine of AT does not rerun (particularly stage in service life or due to fault), and the computing machine of AT no longer transmits the CAN message corresponding with the state of change-speed box, the computing machine of instrument carrier panel just stores the last value of the message corresponding with the parking/non-parked state of change-speed box.
If the computing machine of instrument carrier panel also receives the state of the door of chaufeur, then it oneself and reliably and recalculate " door is opened " consistently and the value of " door is opened " alarm of " non-parking ".
Because instrument carrier panel is permanent power supply, therefore, ensure that and will generate " door is opened " alarm in all stages in service life of vehicle.
The present invention is specially adapted to the automatic gearbox comprising electric parking finger actuator.In this case, the final position of automatic gearbox after the position that the computing machine of instrument carrier panel stores always no longer provides electric power to parking finger: it is the electric position of parking finger when its electric power supply is cut off.
If parking position is subject to the control of mechanical cable, then this position can engage in the absence of a power supply.But, store the parking/non-parking information of change-speed box.Therefore, the position that if instrument carrier panel stores when driving engine is closed " parking not yet engages ", then by chaufeur follow-up action on his or her gear selector, position mechanically can be changed to " parking not yet engages ", and this can not be notified the computing machine of instrument carrier panel.This situation may generate flase alarm, but can not cause the risk of the uncontrolled movement of any vehicle, because change-speed box is fixed effectively.
